摘　　要：三相输电线路导线表面电荷的分布是不均匀的,各点电场强度的大小也不同。文中采用表面电荷法计算导线表面的电荷密度,然后求出导线表面各点的最大电场强度值。计算方法能够反映出电荷密度及电场强度沿导线圆周分布的情况,根据计算结果优化高压输电线路的布置。The distribution of surface charges in three-phase transmission lines is uneven and the electric fields of various points are different.The charge density on the surface of transmission lines was calculated by the surface charge simulation method and the max electric field intensity was evaluated.The calculation can reflect the distributions of electric charges and electric field intensity along the circle of the circuits and optimize the collocation of HV transmission lines.
